' ROTARY PLOW.

Specification of Letters Patent.

, Patented Dec. 29, 1914.

Application filed November 16, 1912. Serial No. 731,662.

left in such a condition as to be ready for immediate seeding and 1t conslsts essentially of a main frame, a cross shaft rotatably supported in the frame, rotary plowing members mounted upon the shaft comprising a series of plowshare arms of peculiar form set in a substantially tangential position to the rotary shaft and means for adjusting the vertical position of the shaft in relation to the ground as hereinafter more particularly explained by the following specification.

Figure l, is a plan view of. my plow. Fig. 2, is a side elevation of Fig. 1. Fig. 3, is an enlarged perspective detail of one of the rotary members. Fig. 4, is an enlarged perspective detail of one of the plowshare arms. Fig. 5, is a cross section on line-me-y Fig. 4. Fig. 6, is a front elevation of one of the plowshare arms. F igs 7, is a sectional detail on line mg Fig. 6. Fig. 8, is a sectional detail on line m Fig. 6. Fig. 9, is a sectional view taken through Fig. 6 on line w y at the point of junction between the tangential and right angular portions of the plowshare arm body.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the main frame provided with suitably supporting wheels A and A V A is a suitable source of power mounted upon the main frame A and provided with a main driving shaft A provided at each end with beveled gears A and A".

B and B are bars swung at one end upon the driving shaft A".

B is a bar connecting the barsB and B together in proximity to the free end thereof.

C is a shaft journaled in the side bars of the main frame A. mounted thereon. I

C is a worm gear mounted upon the shaft C journaled in a suitable bracket (3*. The

C is a worm wheel shaft: C is provided with an adjusting handle C C is an arm secured to the shaft C.

C? is a. bracket secured to the cross bar B and C is a'link connecting the bracket C with the arm C".

Dis a cross shaft journaled in the bars B and B. a F are beveled gears mounted on each'end of the rotary shaft D. i

, F are counter shafts mounted in bearings F 2 extending from the side bars B and B.

F are beveled-gears meshing with the beveled gears F and F t are beveled gears meshing with the beveled gears A E are a series of rotary members mounted upon the shaft C. The members E comprise a central hub D (see F ig. 3) and have tangential arms 1') and plowshare arms D secured by suitable bolts D to the arms D I Each plowshare arm comprises a body portion, such body portion comprising 'a' portion set in a position parallel with the tangential arms of the hub and through which the bolts D extend and a portion D eX- tending from the aforesaid portion at its inner endin a direction at right angles to such portion, the portion D curving gradually at its outer end to the point D.

D is a flange extending at right angles to the portion D and lies throughout its length along one side of the flange D and increasing in height from the point D toward the.

hub and then merges into a plane of the portion D at the junction between the portion D and the tangential portion secured to the portion D of the hub.

D is a flange which engages in the opposite edge of the portion D at a point in the rear of D, such flange is gradually drawn into the center of D and increasing inwardly in height until opposite the point where D merges into D from which point it gradually decreases in height to the inner en It will thus be seen that as the plowpasses serving to force or crowd the earth toward the flange D so as to deliver the earth over the side of the arm at the point where the flange l) merges into the portion D at the inner end of the arm.

To adjust the depth of the cut all that it is necessary to do is to elevate the outer ends of the bars B and B by means of the handle C shaft C Worm C and worm gear 0 mounted upon the shaft 0 carrying the Outer end of the arm C circumferentially and drawing upon the link C and bar 13 thereby elevating the side bars l3 and B and the rotary cutting member carriedthereby.

Although I have described this means for elevating the rotary plow members it will, of course, be understood that there are many other ways by which the same result may be accomplished and also that there are many other ways by which the rotary plow members may be rotated other than that shown by'the drawing and described herein.

V] hat I particularly wish to cover is the rotary plow members which are revolved as above described slicing the earth up and leaving it behind the plow in. a fine almost pulverized condition such as will readily be effected by the action of the atmosphere, the sod being cut up in a fine form which will easily rot and, therefore, obviate the necessity of any further cultivation of the soil before seeding takes place.

What I claim as my invention is:

1. In a rotary plow, the combination with the main frame, of a suitably driven shaft carried by the main frame and rotary plow member's carried by the shaft and comprising a central hub and plowshare arms formed by a body portion comprising a tangential portion and a portion extending at right angles to the tangential portion and provided with a side flange merging at each end into the body of the share arm and a flange extending from the opposite side of the right angular portion of the share arm intermediately of its length, such flange being gradually drawn into the center of the body increasing in height merging at its opposite end into the share body, as and for the purpose specified.

2. In a device of the class described, a rotary plowshare member comprising a central hub, a plowshare arm formed by a body portion comprising a portion secured to the hub and extending tangentially therefrom and a portion extending from such tangential portion substantially at right angles thereto, a side flange extending along one side of the right angular portion of the p'lowshare arm merging at its ends into such arm, and a flange extending from the opposite edge of the rigl'it angular portion of the share body intermediately of its length, such flange being gradually drawn into the center of the body and increasing in height and then gradually merging at its opposite end into the share body, as and for the purpose specified.
